MEANS FOR REGULATING' MOVING TORPEDOES.

Application filed November 11, 1924. seam. 749,352.

To all whom it may concern:

'Be it known that L'Fnerronsoo SOHMID, a subject ofthe King of Italy, residing at Naples, Italy, Via E. Gianturco, Silurificio Italiano, have invented new and useful Improvements in Means for Regulating Moving Torpedoes, of which the following is a specification.

This invention relates to self propelling torpedoes and has for object to provide means for regulating the torpedo, i. e its various organs, from outside, when the torpedo is in its firing position.

The principal object of the invention is to provide means for effecting the various regulations of the different operative organs or meinbers of the torpedo after that the latter has been introduced into the tube and the tube shut, without reopening said tube and withdrawing the torpedo to effect the regulations as the case has been so far, still setting the various organs or members in the proper positions for the actual operation. I

The invention will be better understood referring to the accompanying drawings, in which:

Fig. 1 is an axial sectional view of the rear part of the tube, a torpedo being shown in its position ready for firing or launching.

Fig. 2 is a partial reproduction of the device with the connecting parts out of gearing, and

Fig. 3 is a cross sectional diagraimnatical view taken across the casing, showing the gearing wheel depla-ced in order to allow the free forward and backward movement of the torpedo entering the tube or being withdrawn.

In the drawings only one regulating device is shown, but it must be understood that there shall be as many regulating devices of the kind shown in the drawing as there are organs of the torpedo needing regulation, and that the device according to this invention replaces and substitutes the discs and dials presently arranged on the outside of the torpedo, and that must be adjusted with the present arrangement before introducing the torpedo into the tube, the torpedo requiring at present to be withdrawn at least partially when new regulations are needed at the moment of its being fired or launched.

The device, according to the invention,

consists of parts or members fixed to the the tube; The former consists of a pinion 2 arranged in a recess purposely made in the torpedo shell and partly projecting torpedo and parts or members fixed on to above the outer surface of said shell, and

of a shaft 1 rigidly fixed to said pinion on one endand connected on the-other end with the organ to be regulated, said shaft transmitting to the corresponding organ the movements imparted to said pinion from outside the 'tuberas it willbe declared and specified. 1

The parts of. the device fixed to thetube consist of: a wheel 3 and pinion 4 gearing with one another, a forked member 5011 the end of which is rotatably fixed the wheel ,the said forked bearing 5' being rigidly fixed to the axially slidable and rotatable hollow shaft 6 and carrying between j its jaws the pinion 4; said rotatable member being provided with a prismatic square projection 13 in straight prolongation with the shaft ,6, a lever 7 on the rear end of the shaft 6, a shaft 8 partially set intothe hollow shaft 6 on which the pinion/l is fixed, a dial 9 mounted on a sleeve fixed to the tube, a hand lever 10 with finger 11 that moves along the face of the graduated dial rigidly fixed to shaft 8, awater and air tight casing 12 for'the gearing'34, having a square projecting recessfinto which the square member of the rotatable gearing 5 fits and a support 14; forthe shaft.

. As already stated, in order not to hinder the to and fro movement of the torpedo in the tube, the recesses in which the pinions 2 are placed, are arranged wherethe diameter of the torpedo is smaller-and its tail begins, and in planes other than the vertical or horizontal ones, in order to not interfere with the screw frame of the torpedo, as it acting on said lever 7, the shaft is first pushed forward and then caused torotate in the opposite direction, when the wheel 3 resumes its operating position in which it gears with pinion 2. In this forward movement of the shaft 6, the prismatic projection of the forked member 5 enters into the prismatic recess of the casing 12 securing in this way the gearing position of wheel 3, such position being still rendered surer, by the sleeve that supports the lever 7 abutting under a shoulder of the support 14 (Fig. 1). Once effected the gearing of pin ion 2 with wheel 3,rthe regulation of the torpedo organ is obtained by turning the that need regulation before firing, when the torpedo'is in place in the tube, of a pinion placed in a recess on the torpedo shell, and a shaft fixed to the organ of the torpedo to be regulated, said shaft and pinion lying within the torpedo shell, and a rotatable l element supported by the torpedo tube and movable into mesh with the pinion located within said recess.

s 2. In a torpedo tube the combination with a shaft and pinion in the torpedo of a forked member on the tube having at its end awheel and being fixed to air axially slidable rotatable hollow shaft adapted to be moved to and fro' and rotated by means of a hand lever fixed to the rear end of'said hollow shaft.

3. In combination with a shaft and pinion on the torpedo and a slidable and rotatable hollow shaft on the tube, of a forked member fixed thereto, having a Wheel on its end and a. projection on its forward aw. J a. In combination with a shaft and pinion on the torpedo and a hollow slidable and rotatable shaft on the tube of a Water and air tight casing for the gearing, made with a square recess for the square projection of the forked member on the hollow shaft.

5. In a torpedo and tube, the combination with a shaft and pinion on the torpedo, a hollow slidable shaft having a forked member on its forward end and a water and air tight casing, of a hand lever fixed on the rear end of said hollow shaft, by means of which the hollow shaft and the forked member may be angularly rotated in order to put the wheel out of the way of the torpedo.

(3. In a torpedo and tube the combination of shaft and pinion on the torpedo and a rotatable hollow shaft and forked member on the tube, of a pinion mounted in the forked member, a solid shaft moving inside the hollow shaft, on the forward end of which is rigidly fixed a pinion meshing with the second pinion, and a hand lever and finger moving along the face of a dial fixed on the tube, by means of which lever the internal shaft with the pinion is rotated and movement transmitted to the organ to be regulated.

In testimony whereof I have signed my name to this specification.
